SPECIFICATION forming part of Letters Patent No. 394,179, lat-a1December 11, 1888.

Application filed January 16, 1888. Serial 110,260,950. (N0 model.)

To all whom it may concern:

Be it known that I, ISAAC HAYES, a citizen of the United States,residing in the city and county of Philadelphia, and State ofPennsylvania, have invented a new and useful Improvement in Apparatusfor vaporizing and Burning Non-Explosive Oils for Heating Purposes, ofwhich the following is a specification.

The object of my invention is t": iovide an apparatus wherein any of thenon-explosive or heavy oilssuch as astral or headlight oilmay bevaporized and burned to create heat for any purpose where a ready andreliable heat is requirwl.

My invention consists of a suitable metal box or frame in which arearranged longitudinally a double returi'i system of tubes andfiues,-through which the oil is allowed to flow and become vaporized bypreviously introducing and igniting a small quantity of naphtha in thebox sul'lieient to heat the tubes.

Reference is had to the accompanying drawings, in which Figure l is aperspective view of my invention. Fig. 2 is a vertical transversesection on the line (:1 b of Fig. 1 Fig. 3 is also a vertical transversesection on the line 0 d of Fig. 1. Fig. 4 is a perspective view of myinvention, showing it applied in the fire-box of a cooking-range.

A is a east-metal box or frame of rectangular form, of any suitabledimensions, made concave inside, with the base recessed from the points6 to f, Fig. l, in which is secured a curved sheet-metalscattering-plate, B, with an intervening space for the passage of flame.

C and C are tubes extending longitudinally through the interior of thebox A on each side and within a short distance of the top, andcommunicating with lower returnflues or tubular passage-ways, D and D,made longitudinally through the solid metal of the box.

C and C are vertical tubes located on top and near each end of the box,with their lower ends secured in the orifice of openings E and E, whichextend downward and connect at right angles with the fines I) and D,Figs. 1 and 3. Secured to the upper ends of the said tubes C and C andprojecting horizontally from the same, are two overheadsuperheating-tubes, C and C provided at their opposite extremities withd mvnward-proj ecting burners G and G.

The outer ends of the tubes and (1, which project through the oppositeends of the box, may join and lead to any suitable reservoircontainil'ig non-explosive oil, while the inner ends connect with thelower fines, l) and I), through vertical passages F and i made in themetal at the opposite ends of the box, as shown at I igs. l and 23. Theoil flowing through the tubes in the direction shown by arrows, Fig.l,is first heated to gem-mate vapor by igniting a small quantity olfnaphtha within the box; or naphtha in a limited qua-m tity may besupplied From a small reservoir, after which the [lame l'rom the burningvapor ol' the non-explosive oil will continue to heat the tubes andlines.

and 'ltigs. l and 2, are small apertures made through the bottom of thebox A, directly below the burners G and G, through which a portion ofthe flame passes and im- 'lingcs the scat'terii\g ilate I by which meansthe flame is caused to circulate freely around The sides of the box.

The edges ol. the metal in the recesses at the base of the box andaround the fines D and D are rounded off, and the outer edges of theplate 13 are correspondingly curved to direct a portion of thefiamepassin g through the apertures e and c upward and closer around thelines, as shown in Fig. 2. The flame also impinges the interior concavesides of the box, and is turned upward to completely surround the uppertubes, C and C, thus causing the heat to vaporize the oil readily. Theoverhead tubes 0 and C are also subject to the action of the flameascending from the interior of the box, by which means the oil or "aporwithin them is superheated, thereby causing a more complete combustionat the burners.

My invention may be applied in the firebox of a cooking range, stove, orheater, either above or below the grate; or the grate may be removed andthe fire-box arranged with cross-bars to support the apparatus, as shownin Fig. 4.

Ido not wish to limit myself to the exact number of tubes and finesused, as two or with longitudinal fines D and D, openings E and E,vertical passages F and F, apertures a e, with the tubes 0, C, C C C andC burners Gr and G, and seattefing-plate B,

substantially as and for the purpose herein 15 specified.
